What is a Z-line and Z-loop test?
Discuss What is a Z-line and Z-loop test? in the Electrical Forum area at ElectriciansForums.net
More of a basic question like, "Why do we do a Z-line or Z-loop test?"Are you talking about the options on a test device such as a mft?
If so, Z line measures the impedance Z of the lines R1 + Rn for phase to neutral, and R1 + R1 for phase to phase (depends on your connection)
Z loop measures the impedance of the earth loop - R1 + R2 (line and earth connection)
